These are values that represent the amount of information used to convert analog signals to digital signals. 
They may be expressed as 48kHz/24bit, for example.

This defines the number of samples per second (sampling a finite set of discrete values in an analog 
signal). The higher the sampling rate, the broader the range of frequencies that can be played back.

This defines the amplitude value of sounds when quantifying analog signals as finite values. The higher 
the bit depth, the deeper sounds are reproduced.

This is a video technology supported by the HDMI standard. It processes RGB or YCbCr signals at bit 
depths of 10, 12, or 16 bits per color, whereas conventional formats utilize only 8-bit processing, enabling 
reproduction of more colors. Its gamut is comprised of a billion or more colors, while the gamuts of 
conventional formats are comprised of only millions of colors or less. This broader gamut results in more 
precise reproduction of colors and greater detail in darker portions.

Dolby Atmos is an object-based surround sound technology developed by Dolby Laboratories. Traditional 
surround sound technologies record and control audio for each channel. Dolby Atmos records audio 
content as a collection of many objects (a combination of audio information and information related to 
movement of sound positions) and precisely controls content in accordance with various home theater 
environments for an acoustic environment more realistic and three-dimensional than ever before. Another 
advantage is the ability to record sounds coming from overhead. It was originally developed for movie 
theaters, but can also be applied to home devices. 

Dolby Atmos content is provided in the Dolby True HD format, including Dolby Atmos streams, or in the 
Dolby Digital Plus format.

This is a compressed audio format for 5.1 channels. It was developed by Dolby Laboratories, and is widely 
used with DVD discs.

This technology enables 6.1-channel playback for sources encoded in the Dolby Digital EX format. It takes 
the Dolby Digital 5.1-channel setup one step further with an additional back surround channel.

This is a compressed audio format for 7.1 channels developed by Dolby Laboratories. It is fully compatible 
with Dolby Digital and is available for playback on Dolby Digital-enabled audio systems. It is widely used 
with Blu-ray Discs.

This surround sound technology was developed by Dolby Laboratories to extend 2- to 7.1-channel content 
in accordance with audio systems used for playback. It not only enables playback of Dolby Atmos content 
but also extends traditional audio content to surround sound, including height channel audio, for 3D 
surround sound playback.

This advanced lossless audio technology was developed by Dolby Laboratories for high-definition 
disc-based media to deliver sounds that are identical, bit for bit, to studio masters for a great home theater 
experience. It delivers up to 8 discrete channels of 24-bit/96-kHz (up to 6 discrete channels of 24-bit/192 
kHz) audio simultaneously, and is widely used with Blu-ray Discs.

This is a compressed audio format for 5.1 channels developed by DTS. It is widely used with DVD discs.

This is a compressed audio format for 5.1 channels. It provides a higher compression ratio than the DTS 
Digital Surround audio format, and was developed specifically for network streaming and Blu-ray Disc 
secondary audio.

This is a compressed audio format for 24-bit/96-kHz superior sound quality with 7.1 channels developed by 
DTS. It is fully compatible with DTS Digital Surround, and is widely used with Blu-ray Discs.

This advanced lossless audio technology was developed by DTS for high-definition disc-based media to 
deliver sounds identical, bit for bit, to studio masters for a great home theater experience. It delivers up to 8 
discrete channels at 24-bit/96 kHz (up to 6 discrete channels at 24-bit/192 kHz) audio simultaneously, and is 
widely used with Blu-ray Discs.

This technology enables discrete 6-channel playback from 2-channel sources. There are two modes 
available: “Music mode” for music sources and “Cinema mode” for movie sources. It provides a channel 
split effect similar to sources recorded as discrete surround sound.
